FIELD OF THE INVENTION

The present invention relates to a collecting device for attachment tohuman skin and for collecting bodily waste e.g. an ostomy device.

BACKGROUND

Collecting devices for collecting bodily waste, ostomy appliances, woundor fistulae drainage bandages or devices for collecting urine areusually in the form of a receptacle, e.g. a bag, pouch or tube forreceiving the waste, connected to an adhesive wafer that can be attachedto the skin of the patient. The wafer is typically in the form of abacking layer coated on the skin-facing surface with an adhesive layerand the wafer may further be provided with an aperture for accommodatingthe body opening. The size and shape of said aperture can often beadapted individually to fit the anatomy of the patient.

One of the crucial parts of such devices is the adhesive wafer. Thewafer should be able to fit leak proof around the body opening, havegood adherence to the skin without unintended detachment from the skin,but at the same time be easy to remove again without damaging the skin.Furthermore, the wafer should be able to follow the movements of thebody and be comfortable to wear.

When designing a skin adhesive one of the major issues is to keep theskin relatively dry underneath the adhesive to prevent maceration.Maceration occurs when the skin is unable to get rid of moisture fromtranspiration and outlet from a body opening. This may result indegradation of the skin's barrier function as well as bad adhesion ofthe device to the skin.

Usually, skin adhesive keeps the skin dry by absorbing moisture.Absorbing particles or hydrocolloids (HC) are mixed into an adhesivematrix in order to absorb moisture from the skin and thereby the skin iskept relatively dry. This technique is well known in the art and formsthe basis for most ostomy adhesives that are commercially available see,e.g. U.S. Pat. No. 4,192,785.

To improve the ability of the adhesive wafer to resist leakage, somewafers include a secondary adhesive surrounding a first adhesive center.The first adhesive is positioned adjacent to the output source and thesecondary adhesive supplies additional leakage resistance. U.S. Pat. No.4,775,374 describes an adhesive construction, wherein both the first andthe secondary adhesive are hydrocolloid (HC) based. In this adhesiveconstruction, both the first and the second adhesive are sensitive tothe output that they are supposed to resist. Additionally, they willboth swell when getting in contact with the output. Thus, the failuremechanism is the same for both adhesives and the added protection islimited. Other products, such as the Microskin adhesive with washer soldby Cymed, include a first and a second adhesive where the second outeradhesive is an acrylic adhesive. Acrylic adhesives are known to causeallergic reactions on skin and are therefore problematic. Furthermore,known secondary adhesives strip or otherwise damage the skin uponremoval, which can be painful and discomforting to the user.

It has now surprisingly been found that by combining a standard HCadhesive with a polyethylene copolymer based adhesive system, theproblem with allergic reactions can be avoided. Furthermore, thestandard HC adhesive and the polyethylene copolymer adhesive system arevery different in adhesion properties. Thus, the two adhesivescharacteristics can complement each other to achieve better adhesionthan one of the adhesives could achieve alone. Finally, the polyethylenecopolymer based adhesive system is non-damaging and less painful toremove, providing a more comfortable secondary adhesive.

BRIEF DESCRIPTION OF THE DRAWING

The invention is disclosed more in detail with reference to the drawingsin which FIGS. 1 to 4 show different embodiments of the invention.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

The aim of the invention is to provide a body waste collecting devicethat includes a first adhesive and an additional second adhesive,wherein said additional second adhesive comprises a polar plasticisingoil or a combination of polar plasticising oils in the content of above10% (w/w) of the final second adhesive, and at least one polarpolyethylene copolymer, wherein the content of the polyethylenecopolymer is 10-50% (w/w) of the final second adhesive, the polyethylenecopolymer has a melt flow index below 2 g/10 min (190° C./21.1N).

By body waste collecting device is meant a device being able to collectand hold the output in a collecting item for a predefined time. Theholding in place of the device may be obtained by a skin adhesive andthe collection may be obtained by a bag.

In an embodiment of the invention a body waste collecting devicecomprises a collecting pouch and an adhesive wafer for attachment to thebody, said adhesive wafer comprises a backing layer, a first adhesiveand an additional second adhesive, wherein said additional secondadhesive comprises a polar plasticising oil or a combination of polarplasticising oils in the content of above 10% (w/w) of the final secondadhesive, and at least one polar polyethylene copolymer, wherein thecontent of the polyethylene copolymer is 10-50% (w/w) of the finalsecond adhesive, the polyethylene copolymer has a melt flow index below2 g/10 min (190° C./21.1N).

The polyethylene copolymer based adhesive system does not absorb themoisture but rather permeate the water away from the skin surface. Thus,the swelling effect caused by the hydrocolloids will usually not occur.The adhesion is usually obtained by wetting and affinity to the skin.

The additional second adhesive is used for security and protection forthe user in order to avoid leakages and to obtain longer wear time.

According to an embodiment of the invention, the first adhesive islocated adjacent to the body waste source, usually an ostomy or afistula.

By located adjacent to is meant that the subject is located close to oreven in contact with the other subject.

In one embodiment of the invention, the first adhesive is a hydrocolloidpressure sensitive adhesive.

A standard and conventional hydrocolloid (HC) pressure sensitiveadhesive is a skin friendly adhesive that is capable of adhering to theskin, handling perspiration by absorbing the moist and being removablefrom the skin without essential damage.

A typical pressure sensitive adhesive is based on a polyisobutylene, PIB(adhering substance) and carboxy methyl cellulose, CMC (absorbingmedia).

A typical HC pressure sensitive adhesive as used today is a highlyfilled hydrocolloid system with a matrix of polymers that exhibit flowas well as cohesive properties. The hydrocolloids absorb the moisturefrom perspiration and output from the body and the polymers adhere tothe skin through skin polymer affinity and the polymers flow into thesmall cavities of the skin. The cohesion of the adhesive ensures thaterosion is minimised and that the wafer is removed in one piece and thatminimal adhesive residues are left at the skin.

The collecting device according to the invention combines the mechanicaland adhesive properties of the two kinds of known skin adhesives asdescribed above. A negative effect of the swelling of thehydrocolloid-based skin adhesive is used according to the invention in abeneficial way to provide a sealing effect.

In the use of an ostomy appliance the requirements from the adhesive inthe pen stomal area are often different as the use varies within stomatype, body shape, user patterns etc.

When using a hydrocolloid adhesive as the first adhesive according tothe invention, the peri stomal area of the adhesive wafer tends to bestiffer resulting in a fixation of the skin in the inner part of thewafer and a more soft and flexible part in the outer zone. The slightlystiffer inner zone is typically obtained from the high filler rate ofabsorbing particles and choice of adhesive materials that are stifferthan the additional second adhesive.

Such an embodiment according to the invention is especially beneficialwhen used in cases where very liquid or skin aggressive output isexposed to the inner hole of the adhesive wafer for a long time. Atypical example is the use of a 2-piece appliance for ileo ostomy wherethe adhesive wafer stays on the skin for several days.

The additional second adhesive of the invention comprises a polarplasticising oil or a combination of polar plasticising oils in thecontent of above 10% (w/w) of the final second adhesive, and at leastone polar polyethylene copolymer, wherein the content of thepolyethylene copolymer is 10-50% (w/w) of the final second adhesive, thepolyethylene copolymer has a melt flow index below 2 g/10 min (190°C./21.1N).

According to one embodiment of the invention, the additional secondadhesive is produced by mixing a polar plasticising oil or a combinationof polar plasticising oils in the content of above 10% (w/w) of thefinal second adhesive, and at least one polar polyethylene copolymer,wherein the content of the polyethylene copolymer is 10-50% (w/w) of thefinal second adhesive, the polyethylene copolymer has a melt flow indexbelow 2 g/10 min (190° C./21.1N).

Experimental

Laboratory Methods

Method 1: Determination of Moisture Vapour Transmission Rate (MVTR)

MVTR was measured in grams per square meter (g/m²) over a 24 hoursperiod using an inverted cup method.

A container or cup that was water and water vapour impermeable having anopening was used. 20 ml saline water (0.9% NaCl in demineralised water)was placed in the container and the opening was sealed with the testadhesive film. The container was placed into an electrically heatedhumidity cabinet and the container or cup was placed up side down suchthat the water was in contact with the adhesive. The cabinet wasmaintained at 37° C. and 15% relative humidity (RH). The weight loss ofthe container was followed as a function of time. The weight loss wasdue to evaporation of water vapour transmitted through the adhesivefilm. This difference was used to calculate Moisture vapour transmissionrate or MVTR. MVTR was calculated as the weight loss pr time divided bythe area of the opening in the cup (g/m²/24 h). The MVTR of a materialwas a linear function of the thickness of the material. Thus, whenreporting MVTR to characterise a material, it was important to informthe thickness of the material which MVTR was reported. We used 150 μm asa reference. If thinner or thicker samples were measured, the MVTR wasreported as corresponding to a 150 μm sample. Thus a 300 μm sample witha measured MVTR of 10 g/m²/24 h was reported as having MVTR=20 g/m²/24 hfor a 150 μm sample because of the linear connection between thicknessof sample and MVTR of sample.

Finally, we noted that by using this method, we introduced an error byusing a supporting PU film. Utilising the fact, that the adhesive/filmlaminate was a system of two resistances in series eliminated the error.When the film and the adhesive were homogeneous, the transmission ratemay be expressed as:1/P(measured)=1/P(Film)+1/P(Adhesive)

Hence by knowing the film permeability and thickness of the adhesive, itwas possible to calculate the true permeability of the adhesive(P(Adhesive)) using the following expression:P(adhesive)=d(Adhesive)/150micron*1/(1/P(measured)−1/P(Film))where d(Adhesive) was the actual measured thickness of the adhesive andP(Film) was the MVTR of the film without any adhesive on and P(measured)was the actual measured MVTR.Method 2: DMA and Determination of G′ and Tan (δ)

The parameters G′ and tan (δ) were measured as follows: The adhesiveswere pressed into a plate of 1 mm thickness. A round sample of 25 mm indiameter was cut out and placed in a RheoStress RS600 rheometer fromThermo Electron. The geometry applied was parallel plates 25 mm and thedeformation was fixed at 1% to ensure that measurements were in thelinear regime. The measurements were carried out at 32° C.
